Electric current and magnetism

Level Elementary

Concept

When two magnets are close together, magnetic
forces are at work. Two magnets repel or attract each
other. A wire carrying an electric current and a magnet
also repel or attract, because electric current makes a
magnetic field.

Experiment.

Electric swing

Materials

solder wire, enameled wire, horseshoe magnet, battery, switch, conducting wire and
wooden stick.

Close the switch, what happens?

Question
Change the direction of electric current and switch the magnets.
